Post #1723771

@fugueish@wandering.shop hmm yeah looks like clang hasn't gotten the memo yet. i can get this to work with gcc, but the standard doesn't allow type definitions in "underspecified" `auto` declarations, so i had to write ``` #define $Option(T) struct Option##T { T value; bool valid; } #define $Some(T, v) ($Option(T)){ .value = v, .valid = true } void printOption($Option(int) x) { ... } int main() { // can't use auto $Option(int) o = $Some(int, 42); printOption(o); } ```
